Example 1
Fig. 3 is a flowchart of a first embodiment of the output volume control method of the present invention. An output volume control method, the method comprising:
S1, detecting whether the external audio acquired by equipment contains a preset detection signal or not in real time when the equipment is in an audio output process;
s2, if the external audio is detected to contain the detection signal, the output volume of the audio is reduced according to a preset first volume regulation relation;
s3, continuously detecting whether the external audio contains the detection signal or not after the volume of the audio output is reduced according to the first volume regulation relation;
and S4, if the detection signal is not contained in the external audio, the output volume of the audio is increased according to a preset second volume regulation relation.
Optionally, in this embodiment, the device may be a mobile terminal device such as a mobile phone, and further, when the device is in audio output, it may be understood that an external device such as an earphone or a headset connected to the mobile terminal device outputs audio, and at this time, the user may miss a prompt sound of the external environment because the device is in a closed audio output environment, so this embodiment will specifically solve this problem;
Optionally, in this embodiment, when the mobile terminal device such as a mobile phone is in a position where the handset is receiving a call or the handset is listening to voice information, because the ear of the user is closer to the handset of the device, particularly when the fitting is tighter, the user may miss the cue sound of the external environment due to being in an audio output environment similar to a closed audio output environment, so this embodiment will also solve the problem pointedly;
Optionally, in this embodiment, during the process that the device is in audio output, whether the external audio acquired by the device includes a preset detection signal is detected in real time, where the preset detection signal is voice information that needs to be known and is preset by a user, for example, broadcast information of a railway station, broadcast information of an airport, arrival information of a bus, and the like;
Optionally, in this embodiment, if the detection signal is detected to be included in the external audio, the output volume of the audio is adjusted to be smaller according to a preset first volume adjustment relationship, and it should be noted that, in this embodiment, when the detection signal corresponding to the broadcast information of the train station, the broadcast information of the airport, the arrival information of the bus, etc. is identified, the output volume of the audio starts to be reduced, and is in a continuously reduced state, and at this time, the user can relatively clearly obtain the broadcast information of the train station, the broadcast information of the airport, the arrival information of the bus, etc. in the external environment;
Optionally, in this embodiment, after the volume of the audio output is adjusted according to the first volume adjustment relationship, whether the external audio includes the detection signal is continuously detected, where the purpose of the continuous detection is to enable the user to continuously hear subsequent specific information contents such as the broadcast information of the train station, the broadcast information of the airport, and the arrival information of the bus in the external environment, so that the output volume needs to be kept small for a period of time;
optionally, in this embodiment, after the volume of the audio output is adjusted according to the first volume adjustment relationship, whether the external audio includes the detection signal is continuously detected; if the detection signal is not contained in the external audio, the output volume of the audio is increased according to a preset second volume regulation relation, and it is understood that when a user knows the subsequent specific information contents such as the broadcasting information of the train station, the broadcasting information of the airport and the arrival information of the bus in the external environment, namely, when the subsequent specific information contents such as the broadcasting information of the train station, the broadcasting information of the airport and the arrival information of the bus in the external environment are broadcasted, the user does not need to listen to the external sound any more, and at the moment, the original output volume of the user can be recovered;
optionally, in this embodiment, for setting and determining a detection signal, a reverse sound wave and a window function are used to control the output sound size of the terminal, which can actively detect a specific signal outside the device, so as to actively turn down the sound output volume of the device, so as to ensure that the user cannot influence the acquisition of important information due to the sounding of the device in the process of using the device;
